Connect the Power Cords
Caution –
Your site must have a local power disconnect (for example, circuit
breakers) between the power source and the power cords. Ensure that these circuit
breakers are set to off before connecting the power cords.
Caution –
Ensure that you install the server near your power grid’s electrical
outlets, and ensure that these outlets are easily accessible in case you must detach the
power cords in an emergency.
Caution –
This safest and preferred way to supply power to the server is to install
the power cords while the power source circuit breakers are set to off. If you do not
have access to the circuit breakers and the facility power cannot be switched off, only
connect the power cords to the AC input filters at this time. When you power on the
server for the first time, connect the IEC 60309 power cord plugs to the live facility
power grid sockets.
The server receives power from six power cords. The server is designed to receive
power from two separate power grids, with three power cords receiving power from
one power grid and the remaining three power cords receiving power from a second
power grid. You must connect all six power cords.
Note –
To aid installing and servicing the power cords, label both ends of the power
cords with the number of the AC input filter (AC0, AC1, AC3, and so on) or with a
number specific to your facility.
1. Prepare to connect the power cords:
■
Review the
“Power Cord Specifications” on page 32
to ensure that you received
the correct power cords for your facility.
■
Review the
“Power Cord-to-Power Supply Relationship” on page 40
to
understand which power cord supplies power to which power supply.
■
Review the
“Facility Power Requirements” on page 37
■
Review the
“Circuit Breaker Capacity Requirements” on page 43
to ensure that
the circuit breakers accommodate your facility power infrastructure.
